Fe-Based Centrifugal Casting Alloy Powder

Iron-based alloy powders provide a cost-effective solution for producing hard, wear-resistant internal surfaces on ferrous components.

The Fe-Cr-C-Ni-Si alloy systems shown in this product family cover approximately 58-62 HRC, depending on composition and processing conditions. Chromium and carbon contribute to hardness and carbide formation, while nickel can improve toughness and metallurgical performance.

برنامه های کاربردی معمولی عبارتند از engine cylinder liners, cylinder sleeves, bushings, wear sleeves and internal bore surfaces requiring high hardness and abrasion resistance.

Ni-Based Centrifugal Casting Alloy Powder

Nickel-based centrifugal casting powders provide a combination of wear resistance, corrosion resistance, metallurgical compatibility and elevated-temperature performance.

Depending on alloy composition, the available Ni-Cr-Si-B / Ni-Cr-Co-Mo-W systems cover approximately 45-63 HRC. These alloys can be selected where iron-based materials cannot provide sufficient corrosion, thermal or tribological performance.

برنامه های کاربردی معمولی عبارتند از high-performance cylinder liners, industrial sleeves, bushings, internal wear surfaces and severe-service rotating machinery components.

Ni-WC Centrifugal Casting Composite Powder

Nickel-tungsten carbide composite systems are designed for particularly severe abrasive and erosive environments.

The nickel-based metallic matrix provides metallurgical bonding and toughness, while WC (tungsten carbide) provides extremely hard wear-resistant reinforcement. Different carbide contents can be selected to balance wear resistance, toughness and processability.

این پودرها به ویژه برای heavy-duty cylinder liners, mining machinery, oilfield components, wear sleeves and industrial components exposed to abrasive particles or severe sliding wear.

Co-Based Centrifugal Casting Alloy Powder

Cobalt-based alloy powders are designed for applications requiring wear resistance, hot hardness, corrosion resistance and stability at elevated temperatures.

Co-Cr-Mo and related cobalt alloy systems are suitable for high-value components subjected to combinations of heat, friction, corrosion and mechanical wear.

برنامه های کاربردی معمولی عبارتند از high-temperature sleeves, valve-related components, engine components and severe-service industrial wear parts.
